Problems solved by technology

After liquefaction and saccharification of corn starch, the DE reaches more than 98%, while the liquefaction and saccharification of rice starch is difficult to complete, and there are many impurities, so it is difficult to make glucose for injection
[0003] The source of rice is more extensive. If it can be used as raw material to prepare glucose for injection, the application prospect will be broader. Therefore, there are currently patents for the method of making glucose for injection from rice. The cost of the process is relatively high. If industrial production is carried out, based on the price of glucose for injection in the domestic market, there will be almost no profit or even a loss. Therefore, it is necessary to open up the international market

Abstract

The invention discloses a method preparing glucose raw material from broken rice for injection and preparations. The broken rice is generated by milling rice and contains bran powder. The method comprises the following steps: performing quality analysis of broken rice; pulverizing acceptable material, pretreating to remove impurities, blending, and liquefying with alpha-amylase; and saccharifying with saccharifying enzyme and pullulanase; removing impurities with activated carbon, performing ion exchange' removing impurities with activated carbon again; and performing nanofiltration and refinement to remove macromolecular compounds, and crystallizing to obtain glucose. From the second impurity removal with activated carbon, the procedures are all conducted under the environment meeting injection preparation requirements. Glucose raw material meeting injection standards is firstly prepared and then blended with liquid under the environment meeting transfusion requirements to be prepared into different types of injections. The broken rice as the raw material is easily-accessible, has low cost, and can be changed into valuables. The method has simple operation process and high product purity, is applicable to industrial production, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of biology and pharmacy, and in particular relates to a production process for making glucose raw materials and preparations for injection from crushed rice. Background technique [0002] Most of the currently used glucose raw materials for injection are made from corn, which is prepared by double-enzymatic hydrolysis of starch, and some are prepared from starch from cassava. Corn contains less protein and has a large starch particle size, while broken rice and rice contain 6.0-10.0% protein, the starch particle size is small, and the starch and protein combine to form a tight network structure that hinders the hydrolysis of starch by α-amylase The disadvantage of incomplete hydrolysis occurs, so the gelatinization temperature is required to be high, above 85°C; while the gelatinization temperature of corn starch is low, and it is easy to liquefy. After liquefaction and saccharification of corn starch, the ...
